OTR: My Husband Has A Pacemaker. Can He Use The Microwave?

Pacemakers used today have shields or guards to protect against
electrical interference from appliances. Even if they were not shielded,
it is still safe because microwaves cannot cause changes in the
structure of food or in the human body. A seal around the door
keeps the microwave energy inside the oven. When the microwave
oven goes off, the microwaves are gone.
